Hydrologic Cycle (ေရသံသရာ)



Hydrologic cycle (ေရသံသရာ) : natural phenomena undergone by water.
Precipitation (ရြာက်ျခင္း) : change of water vapor to liquid water.
Condensation (ေငြ႕ရည္ဖြဲ႕ျခင္း) : formation of clouds.
Immediate evaporation (႐ုတ္ျခည္းအေငြ႔ျပန္ျခင္း) : change of water to water vapor immediately after precipitation, therefore, in the air.
Transpiration (ပင္ေငြ႕ျပန္ျခင္း) : evaporation of water from trees and plants.
Evaporation (အေငြ႕ျပန္ျခင္း) : change of water to water vapor.
Runoff (ေလ်ာက်စီးဆင္းျခင္း) : drainage of water on the ground.
Surface evaporation (မ်က္ႏွာျပင္ အေငြ႕ျပန္ျခင္း) : evaporation of water from the surface of the soil.
Absorption by roots (အျမစ္ျဖင့္ စုပ္ယူျခင္း) : removal of water from the soil by roots.
Infiltration (စိမ့္ဝင္ျခင္း) : absorption of water by the soil.
Surface infiltration (မ်က္ႏွာျပင္စိမ့္ဝင္းျခင္း) : absorption of water by the top layer of the soil.
